shared storage: Prevent mounting shared storage from non-trusted client
gluster shared storage is a volume used for internal storage for
various features including ganesha, geo-rep, snapshot.
So this volume should not be exposed to the client, as it is
a special volume for internal use.
This fix wont't generate non trusted volfile for shared storage volume.
